When an object or figure to be divided into two equal halves, such that the part coincides with the other, is called symmetrical. If a line divides a given figures into two halves, the line is called line of symmetry or axis of symmetry.
first of all a swiss mathematician euler gave an idea to represent a set by the points in a closed curve. Later on British mathematician john venn brought this idea to practice. Such the diagrams drawn to represent sets are called venn ealer diagrams or venn diagram. In venn diagrams the universal set u is … Read more
